Cauliflower Casserole is a low carb, keto friendly side dish that’s packed full of flavor. Chopped Cauliflower is mixed with OMG! Caramelized Onion Dip and Sour Cream. We then top it with a three cheese blend of Monterey Jack, Cheddar, and Parmesan. This is a side dish that’s good enough to have as an entree!
